Hello. I am scheduled for a second polygraph that is supposed to be "specific issue" with respect to drug use. I apparently was found inconclusive on my first test and was asked to take another.

I am curious if anyone knows how a specific issue test is formatted and what kind of relevant questions I can expect. Is there anything I can do to assure myself of passing this time without any question marks? (pro-polygraphers need not respond)

Thanks!
